Where we work in Diamond Bar
Much of Diamond Bar is made up of two-story tract and semi-custom homes with attached garages, such as those in Pathfinder and the Sunset Crossing and Summitridge areas. Older deadbolts in 1970s homes can wear out and stop retracting in the heat, and we can rekey or replace them on site, in ZIP codes 91765 and 91789. Many homeowners are also upgrading to electronic and smart deadbolts, and we install and set them up.
The Country Estates is a guard-gated enclave of large hillside custom homes with high-end entry hardware, keypad gates, and multi-point patio-door locks. A lockout there calls for a technician who can work the perimeter gate keypad and a high-security front-door lock without marring finish hardware. Near the SR-57/SR-60 interchange at Grand Avenue, we also serve office suites and strip centers around Diamond Hills Plaza, including after-hours key extraction and new cylinders in aluminum-storefront doors. We also help residents and visitors near Diamond Bar Center, Diamond Bar Golf Course, and Sycamore Canyon Park.
